[gentoo-user] Compiling on SMP machine?
Got a dual athlon machine with a SMP kernel and have MAKEOPTS=-j 3 in my make.conf when I emerge something and the source is compiling I am only ever using 100% of a single CPU while the other sits idle. If I have the ksim CPU usage meters running while its cooking you can watch the load being switched from one to the other evertime gcc starts with a fresh file. Any ideas on what I should be doing to get it using both CPU's 100% at the same time?

It can't hurt anything. -- Andrew Gaffney -- [EMAIL PROTECTED] mailing list

Hi !
I have a dual celeron and it works.
Some packages will only compile on one CPU (then the -j3 is replaced by -j1 in
the ebuild MAKEOPTS=${MAKEOPTS} -j1)
I remember some kde-packages which do this: arts, kdelibs :-( and so on
Do you have your 1-CPU problem with every package?
I don't know ksim, but the programm top uses a cumulative mode.
You have to press 1 to get each CPU seperate.
Some other questions only for my interest:
Which board do you use? Have you XP or MP?

well i only noticed it last night while installing some kde stuff so that
might be it, will have a play and see

Gigabyte 7DPXDW
http://tw.giga-byte.com/Server/Products/Products_GA-7DPXDW-P.htm
With 2x athlon 2200+ MP and 1GB of ECC ram. Water-cooled with 1/2 tubing,
danger den waterblocks and a whopping ehiem pump - fan noise was driving me
mad :)
Thought about modding some XP's but didn't feel brave enough, metallic paint
would make it tricky to RMA them should I need to.
Very happy with it actually, makes for a kicking workstation. Cannot see me
going back to a single CPU machine ever again.

I second that. I have a pair of 2400 MP's (also too scared for metalic
paint). I also have fans due to the expense of liquid cooling - my tower
hovers about 2 inches off the ground :-)
I have noticed that many compiles override the MAKEOPTS, which I guess is fair
enough if the authors believe that it wont compile using multiple jobs. My
understand is:
Two files:
a.cpp - creates shared object a.so
b.cpp - creates executable b, but requires a.so to link
Therefore if the two jobs of compiling a.cpp and b.cpp start simultaneously,
linking of b.cpp will fail.
My specifics will probably be a little off there, but I believe it is the
correct jist.
